I just shipped four wheels and tires for under $210 and that was half way across the country and with $1,000 insurance on each wheel
. UPS (not the UPS store or any of those wrap and pack places) is a wonderful thing. In the future, should you want to sell the rims and tires again, all you need to do is place thick cardboard on both sides of the wheels/tire assembly and tape them together. UPS will ship them just like that without a problem. As the rims/tires for the Cobra are a bit on the larger side, trying to strap them together brings them over the UPS weight limits and costs increase dramatically.
Hope you find this helpful.
Sincerely,
Bill S.
